Man convicted of murder in 2015 NYC police officer slaying

NEW YORK – A man was convicted Thursday of fatally shooting a New York City police officer in 2015, an act described by a prosecutor as "remorseless."

Demetrius Blackwell, 37, was found guilty of murder and other charges in the death of police Officer Brian Moore, the son of a New York Police Department sergeant.

The 25-year-old officer and his partner were in street clothes in an unmarked car when they attempted to stop Blackwell, who was suspected of carrying a handgun. Authorities say the Queens resident opened fire, striking Moore in the head. He died two days later and was posthumously promoted to Detective First-Grade. His partner wasn't hurt.

"At the end of the day, there was justice done for Brian's killing but it is a hole and it is a void that will never ever be filled," said Irene Moore, the victim's mother.

In closing arguments following a three-week trial, prosecutors said Blackwell was more concerned about who won the Floyd Mayweather-Manny Pacquiao bout as Moore lay dying at a hospital.
